Shrang Fong Dong (shrang feng dong) 'Two Winds Cave' Description By Pete Francis Two Winds Cave is situated 20m above the road near to Di feng (The Great Crack). It represents, however, a much earlier hydrological feature than Di Feng, forming an underground conduit that must predate the lowering of the main Tian Jing Gorge and the incision of Di Feng. The cave gets it's name from the strong draft that comes from the entrance. Immediately inside a fossil trunk passage is met with much breakdown evident. Apart from one or two exceptions the passage is devoid of formations, but there is some evidence of nitrate workings in the form of a crude path and a couple of pits. The cave is formed in beds averaging a metre in thickness and there is an impressive rubble cone in the farthest reaches. At this point the cave terminates in a high fossil passage which has been invaded at a lower level by an immature, misfit stream. The streamway is still active and was not pushed to it's end. Apart from this active, invasive series, the cave is a wholly fossil phreatic cave with features on a scale to be expected in China. |
